A CORPORATION OF NEW WORK-SUPPORT FOR SHOE-MACHINES.

Specification of Letters Patent.

Patented Apr. 29, 1913.

Original application filed February 8, 1899, Serial No. 704,978. Dividedand this application filed June 28.

Serial No. 21,959. Renewed May 4, 1909. Serial No. 493.931.

To all whom it may concern:

Be it known that I, JOSEPH E. Curse, a citizen of the United States,residing at Somerville, in the county of Middlesex and State ofMassachusetts, have invented certain new and useful Improvements inWork- Supports for Shoe-Machines, of which the following is aspecification.

The present invent'onrelates to machines for operating upon boots andshoes, and more particularly to a shoe supporting ack and means foractuating the same to hung the shoe supported thereon into proper osition with relation to the tool or tools 0 the machine as the point ofoperation of the tool or tools is transferredaround the shoe.

The object of the invention is to provide a shoe supporting jack andactuating mechanism therefor of improved'and simplified construction andmode of operation whereby the jack may be actuated to bring the shoeinto the proper position with relation to the tool as the point ofoperation of the tool is transferred around the shoe, and whereby theactuating mechanism may be readily and conveniently adjusted foroperation upon different styles and sizes of shoes.

lVith the above objects in view, the invention consists in the featuresof construction and combination of parts hereinafter described andclaimed, the advantages of which will be readily understood by thoseskilled in the art.

In the drawings :-Figure 1, is a front elevation showing thejack-presenting mechanism and the presser-foot,'or gage for height,which is mounted on the co-acting mechanism and operates in combinationtherewith, also showing the jack in side ele vation and a last indicatedby dotted lines clamped therein. Fig. 2, is a side elevation of Fig. 1,also showing a portion of the co-acting mechanism, and the jack in endside elevation of a set of the supportingtable guide-rolls. Fig. 8, isan enlarged plan of the end-turning devices. Fig. 9, is an enlarged planof the combined pawls and carriers for the jack-feed mechanism. Fig. 10,is a side elevation of Fig. 9. Fig. 11, is a front elevation of Fig. 9with the ratchet feed-pawls removed. Figs. 12 and 13, are enlarged plansof the segments which govern the movements of the co-acting mechanismwhen the jack is swinging from side' to side, showing the two extremesin their construction.

The invention is illustrated as embodied in a lasting machine, thelasting devices of which are the same in construction as the devicesshown in Patent No. 1,018,965, dated February 27, 1912, of which thepresent application is a division. It will be understood, however, thatthe invention is not limited in its application to this type of machine,but maybe embodied in machines for performing other operations uponboots and shoes.

Upon the base of the machine 1 the stands 2 and 3 are fixed, and formedupon or fixed to the inner sides of these stands are .the bearings 4 and4", in which the main driving-shaft 5 and its attachments are mounted.Figs. 1, 2 and 3. A sleeve 7 is fitted to turn free on the shaft 5 andin the bearing 4 fixed to the jack-supporting stand 2, and on the innerend of this sleeve there is the sliding-clutch 8 which connects thesleeve to the belt-pulley 6 when it is desired to operate the machine.The gears 9 at the inner end of the main-shaft serve to actuate theco-acting mechanism in unison with the feeding and presenting mechanism.Outside of the bearing 4 of the stand 2, a mitergear 10 is secured tothe sleeve 7, and its mate 12 is mounted in the bearing 11 and forms theconnection to operate the jackfeedin mechanism. The lower end of theextenslble-shaft 13 is fixed in the gear 12 and the upper end of thisshaft is mounted in the bearin 14 secured to the table 15 of the jac-presenting mechanism. Above the bearing 14 the shaft 13 is providedwith a crank 16 whose crank-pin carries the large roll 17 which operatesthe jack-feed mechanism. Figs. 3 and 5. The jack-feed mechanism movesthe jack horizontally by a combination of right angular steps whenmoving the sides of the lasts (clamped in the ack) by the point ofaction of the co-acting machine, and swings the jack around, from sideto side, when moving the ends of the lasts with reference to the same.point. If the ends of the lasts are a true circle the movement is thatof pawl and ratchet-wheel, step by step; if the ends of the lasts areother than true circles, ovals, square or pointed, etc., which they mostalways are, the movement is by a series of oblique steps which vary foreach different shape of end. The jack-feed mechanism can be adjusted forlength. or width from any determined size or shape, pantographically orotherwise as desired, and it can be constructed to move the jack in anydesired lines without reference to the shape or ourvature of the lastclamped in the ack. The horizontal movements of the jack-feed mechanismare governed by camsone for length which is a fixture, and one for widthwhich is correct for rights and lefts of a series of the same style oflasts, and which is changed for style.

The jack-feed mechanism is constructed and operates as follows :Thewidth adjustments are made by moving the plate 18 horizontally in andout on the table 15 with reference to the point of action of thecoacting mechanism. Figs. 2, 3, 4and 5. Thetable 15 is provided witharallel grooves 19 on its upper face, and in each 'of these grooves aset of rolls 20 are fitted to run whose distance apart is'maintained bysuitable spreaders. Figs. 6 and 7. The sets 6f rolls are fitted to thegrooves 19 so that their ends will contact with the sides of thegrooves, and the rolls roject about-twofifths of their diameter a ovethe top of the table 15 where they engage in a similar man ner with thegrooves 21 formed in the under side of the plate 18, the relation ofgrooves and rolls being clearly shown in Figs. 1, 2, 3, and 5. Thiscombination of rolls and grooves permits the plate 18 to reciprocatefree to and from the devices operating upon the last, and at the sametime causes the plate to move on the table 15 perfectly parallel withits longitudinal center line. The plate 18 is connected by the link 22to the end of the oscillating-lever 23 which is provided with theadjustable-fulcrum 24 and is swung in one direction by a cam and in theother direction by the action of springs, which always keep the cam-rolland the face of the cam in contact. This combination gives accuracy ofmovement regardless of lost motion of parts.

The adjustable-fulcrum 24 is pivoted to swin on the slide 25 whichslides in the stan 26, the stand being formed upon or attached to thetable 15, and the screw 27 is mounted in a projection of said stand togive and maintain the set position of the fulcrum 24. The lever slidesin the fulcrum 24 and at the outer end of the lever there is mounted ofthe ratchet-wheel at all times.

the grooved cam-roll 28, and pivoted to the cam-roll pin is one end ofthe link 29, whose other end is pivoted to the stand 26 at 30.

By this combination the roll end of the lever co-acting mechanismbetween the points of turning the jack to present the ends of the lasts..The other segments of the cam 31 are formed to move the jack-support toand from the same point when it is swinging from side .to side, if theends of the'last 0perated upon are other than a true circle. The cam 31is mounted upon the steady-pins 32 fixed in the plate 33, Fig. 4, and isheld thereon by the groovedcam-roll 28 which causes it to maintain ahorizontal position as it revolves.

Each style of work requires a width-cam adapted to that. style, and whenit is desired to change the action of the cam from right to left or viceversa, the cam is turned over; this may be done by swinging the groovedcam-roll clear of the edge of the cam against the action of the springswhich hold the roll against the face of the cam. The plate 33 is fixedto the upper end of the shaft 34 which is mounted to revolve in abearing formed at the outer end of the bracket 35, and to the lower endof this shaft there is fixed the ratchet-wheel 36 which gives a stepby'step movement to the widthcam. The ratchet-wheel 36 is operated bythe pawl 37 which is pivoted to the groovedblock 38 fixed to theslide-bar 39, and on the opposite end ofthis bar is fixed the camplate40 which is actuated by the cam-roll l7, and each revolution of theshaft '13 causes the ratchet-wheel to advance one step. The pawl 37 isprovided with the lever 41 upon which the spring actuated plunger 42acts to press the pawl 37 toward the teeth The inward movement of theplunger 42 is limited and when it has reached its limit of movement, italso acts to press the end of the pawl 37 firmly into the teeth of theratchetwheel 36 and thus lock it until another movement is required. Theratchet-wheel is also provided with the usual retainer-pawl (not shown)to prevent retrograde movement.

The springs 43 are secured to the table 15 at 44, and to their otherends are secured the short ends of the bell-crank levers 45, which arepivoted to thetable at 46. To the long ends of the bell-crank leversthelinks 47 are pivoted whose opposite ends are pivoted to the under sideof the plate 18. This transmits the stress of the springs 43 to theplate 18 and then through the medium of the link, 22 to theswinging-lever 23 and the cam- 1 roll 28, the springs 43 being strongenough to insure the contact of cam and roll under all conditions ofoperation.

lVhen the oscillating-lever 23 has the adjustable-fulcrum 24 located inits center the extreme width movement is given by the operation of thecam 31. By moving the fulcrum away from the cam the movement of thelever 23 at the end connected to the link 22 can be decreased in anyrequired ratio, the swing of the lever 23 being constant at the endcarrying the cam-roll (by reason of the link connection 29) and variableat the end connected to the link 22.

The jack-support and. its attachments are.

moved longitudinally and swung around on the plate 18 to present thesides and ends of the lasts to the acting mechanism by the followingdescribed devices attached'to the plate 18 and the base of thejack-support. Figs. 1, 2, 3, 4 and 6. On the top of the plate 18 in thecenter there is pivoted the roll 48. The base of the jack-support is athin plate 49 provided with the slot 50 which engages with the roll 48and alines the longitudinal movements of the jack-support. Fixed to thebase of the jack-support 49 are the parallel ratchet-racks 51 which aremade the length of the shortest last of the series to be operated uponbetween the points of turning for operation on the heel or toe. Fittedtoslide between the base 49 and the racks 51 are the ratchet-racks 52connected by% semi-circular ratchet ends. These racks are made thelength of the longest last of the series between the points of turningfor operation on the heel or toe, and the diametrical line of thesemi-circular ends of the racks is provided with semi-circular recesseswhich engage with the roll 48, as shown by Fig. 8, during the time thejack is swinging from side to side.

To operate the racks 51 and 52 theratchetpawls 53 and 54, Figs. 2, 3, 4,9, 10 and 11, (whose working faces .are somewhat longer than the rangeof motion of the racks 52 under the racks 51,) are mounted in thepawl-carriers 55 and 56 upon the slidingpins 57, and are provided withsuitablesprings which press the pawls toward the racks. The pawls andcarriers are tongued and grooved together, as shown by Figs. 9,

l0 and 11, so that 53 and 55 can be moved on 54 and 56 parallel to theirline of reciprocation which is parallel to the longitudinal center lineof the table 15.

The carrier 56 which operates the pawl 54 is fixed to the slide-rod 58,to one end of point of action of the 00- which is fixed the block 59provided with the rolls 60. These rolls engage with the groove in theblock 38 and cause the carrier and its attachments to reciprocate inunison with the pawl 37 operating the width-cam 31, and at the same timeallow the plate 18 to move in and out on the table 15.

The carrier 55 which operates the pawl 53 is provided with the slot 61which is set at an angle of forty-five degrees to the line of movementof the carrier 55 and the pawl 53 on the tongues and grooves, and theslideblock 62 is fitted to slide in this groove. On the top of thecarrier 56 there is the dove-tail slide 63 which can be reciprocated inthe carrier at right-angles to the tongues and grooves, and to thisslide 63 the slide block 62 is firmly fixed; the flanged top of theslide-block acting to hold the two carriers and their attachments insliding contact. When the slide 63 is reciprocated in the carrier 56 theblock 62 acts on the an gular-slot and causes the carrier 55 and thepawl 53 to reciprocate on the tongues and grooves, as will be understoodby reference to Figs. 4, 9, 10 and 11. The slide 63 is reciprocated bythe cam 64 which is operated by the ratchet-wheel 64 and the pawl 64,which are connected to and move in unison with the rod 58 and itsattachments, the connecting mechanism between the slide 63 and the cam64 being substantially the same as that described in connection with theca 31 and the plate 18.

The length-cam 64 serves for all styles of lasts and revolves twice foreach full revolution of the jack-support causing its oscillating-leverto make an active movement when the pawl 53 is moving either of theracks 51, and a return movement when the jack-support is swinging fromside to side and moving the ends of a last by the point of action of theco-acting mechanism.

When the adjustable-fulcrum of the length movement lever is set oppositethe center of the slide 63 there is no movement given to said slide bythe action of the cam 64, and the block 62 acts to lock the carriers 55and 56 together and they are reciprocated as one by the slide-rod 58,the effect on the longitudinal movement of the jack-support being thesame as if the racks were a fixture thereto, and the result being tobring the endturning ratchets into action to turn the longest last ofthe series, the distance between whose points of turning is the lengthof the racks 52. When the shorter lasts of the series are to be operatedupon, the adjustablefulcrum of the length governing lever is moved tothe right to allow the pawl-carrier 55 to move tothe left on the top ofthe pawl-carrier 56 the difi'erence in length between the longest lastof the series and the one to be operated upon. For instance for amachine designed .to operate on lasts om.

size four to size thirteen inclusive, the movementof the carrier 55 andthe pawl 53, to the left, on the carrier 56 and the pawl 54, (during thetime the racks 51and 52 are moving between the points for turning theshortest last of the series,) would be three inches and the length ofthe pawl about four inches. This position of the adjustablefulcrum ofthe length movement lever is substantially shown in Fig. 4, and the fulloperation of the mechanism for either of the shortest longitudinalmovements of the jacksupport, is as follows :At the termination of theend-turning movement of the jacksupport the racks 51 and 52 are at theextreme limit of their movements, to the left, with the center of anend-turning ratchet coincident with the center of the roll 48, and thecenter of the toe or heel in the jack vertically above said center. Withthe jack removed as in Fig. 4, one of the rounded ends of the plateconnecting the racks 51 would just reach to the base of the end-turningratchet-teeth and the other end disclosing nearly all of one ofthe-pawls 65 and its attachments. At-the same time the action of the cam64 has caused the length-movement lever to move the slide 63 to the fulllimit of its backward movement and the block 62 is moved to the rear ofthe angular-slot 61. This causes the pawl 53 and the carrier 55 to moveto the limit of their movement, to the right on the top of the pawl 54and carrier 56.

v\Vhen the action of the .ratchet-pawls 5,3

and 54 commence to move the racks 51 and 52 to the right, the action ofthe cam 64 and its described connections allow the pawl 53 and thecarrier 55 to move to the left on the pawl 54 and the carrier 56 afractional portion of a single ratchet-tooth for each reciprocation ofthe pawls and carriers. The denominator of this fraction is the lengthof the longest last of the series between the points of turning for theheel and toe, and the numerator is the difierence between this lengthand the corresponding length of the last being operated upon. "Were therespective lengths seven and ten inches, the fraction would bethree-tenths, and the pawl 53 and the carrier 55 would have moved to theleft on the pawl 54 and carrier 56 three inches at the termination ofthe longitudinal movement of the jack-support. As the jack-support isswinging around the pawl 53 and carrier 55 make a return movement to theright the termination of which brings the slide-block 62 again to therear end of the slot 61 and causes the pawl 53 and the carrier 55 toproject an equal distance over the right side of the pawl 54 and thecarrier 56, as at the commencement of the active movement, ready toengage with the other rack 51 and move the other side of the last, asdescribed. 'Between the extreme points of movement described movement ofthe adjustable-fulcrum of the length-lever will give any desiredadjustment to move the jack-support the same number of steps for anylast of the series. That is, the racks 51 move the jack-support avarying distance in a given number of steps of varying length and theracks 52 move the end-turning ratchets an invariable distance in thesame number of steps which correctly position said ratchets for theendturning movement, regardless of the length of the steps made by theracks 51. That is to say, the jack carrier is moved endwise a distancevarying with the length of the last while the rack 52 is always moved adistance equal to the distance between the semicircular recesses whichengage the roll 48 when the semicircular ratchet ends of the rack areconcentric with the roll.

When the jack is carrying the longest last of the series and thejack-support is swinging around, the ends of the slot 50 and thesemi-circular recesses of the end-turning ratchets coincide, and one'ofthe ends of the slot and one of the recesses are in contact with theroll 48 fixed on the plate 15, as in of the slot 50 will not contactwith the roll 48 and the action of centrifugal force would move theracks 51 and the jack-support out from the desired position unless somemeans were used to prevent it. In the present instance, these means arethe ratchet-pawls 65 provided with the bell-cranks 66 and pivoted at 67in suitable recesses formed in the sliding-racks 52, as shown by Fig. 8.The springs 68 act to swin the ratchet-pawls away from their engagingracks 69, which are formed upon or attached to the supporting parts ofthe racks 51.

The variation in the lengths of lasts is by one-half sizes and as themovementof the racks 52 under the racks 51 for varying sizes is madewith reference to the transverse center line of the jack-support, fromthe position shown in Fig. 4 the pitch of-the ratchetpawls 65 and theracks 69 should be one-half of said half-size to correctly locate theendturning ratchets under the racks 51 each side of the transversecenter line of the jack. When the roll 48 is brought in contact with oneof the recesses of the racks 52 it depresses the sprin at that end bycontact with one of the be l-cranks as shown by Fig. 8, and swings oneof the awls 65 in, to engage with one of the rac 69. This auto maticallylocks the racks 51 on the racks 52 1,060,282 iii;

18 which in combination wit-h the r01 48 acts to guide the jack-supportduring its straight journeys.

By the preceding description it will be seen that the sliding racks 52are moved in straight lines 'by the action of the pawl 54 with the roll48 as a center until oneof the semi-circular recesses of the end-turningratchets contacts with said roll, as shown by Fig. 8, when theyare swungaround said roll (by the action of the pawl 54 on one of the end-turningratchets) in a semi-circle for another straight journey; the onlyfunction of the racks 52 being to correctly locate the end-swingingratchets which swing the jack-support from side to side.

The length position of the jack-support, with reference to the racks 52is determined by the set position of the fulcrum of theoscillating-lever operating the slide 63, which positions the racks 51;whose only operative function is to move the jack-support in straightlines which vary in length as do the lasts clamped in the jack betweenthe points of turning for the operations upon the heel or toe." Theaction of the length-cam 64 and its connections varies the length ofthose lines by permitting the pawl 53 and its carrier 55 to move orslide back on the pawl 54 and the carrier 56 the difference in lengththe last operated upon is shorter than the longest last of the seriesthe racks 52 aredesigned for. The only operative function of thelength-cam 64 is to reduce the distance the jack-support moves theshorter lasts endwise, and to divide the reduction equally between theteeth of the racks 51. The width position of the jack-support isdetermined by the cam 31, and the width graduations by the set positionof the fulcrum of the oscillating-lever 23 operated by said cam.

Each time the extensible-shaft 13 is revolved the width-cam 31 and itsconnections move the jack-support a step to or from the point of actionof the co-acting mecha-' nism, and the length-cam 64 and its connectionsmove the jack-support a step forward; the combination of the tworight-angular steps being a point. of the curvature of the sides of thebottom of a last where action is desired.

The jack 71 is located on the top of the racks 51 by the steady-pin 72shown in Fig. 4. from which it can be removed at will, its specialfunction being to bring the median line of lasts, either rights orlefts, in correct vertical alinement with the center line of the slot 50of the base of the jack-support.

With a last correctly clamped in the jack, the teeth of the racks 51represent one point of action of the co-acting mechanism for each toothbetween the points of turning the jack for operation upon the heel ortoe.

These areof varying size, some toes not requiring more than threeactions, others perhaps twelve, which is about correct for most heels.

As herein shown and described 2, 3, 4, 6, 8 or 12 points for action canbe presented to the co-acting mechanism as the last is swung from oneside to the other. This is accomplished by automatically stopping theaction of the co-acting mechanism when the pawl 54 is operating theratchet-ends of the racks 52 to allow said pawl to move the ratchetends2, 3, 4, 6, 8 or 12 teeth between each action of the co-actingmechanism; the number of teeth in the ratchet-ends being the leastcommon multiple of those numbers. This mechanism is illustrated in Figs.1, 2, 12 and 13 of the drawings, and is constructed and operates asfollows :-The ratchet-wheel 73 is mounted to revolve on theack-supporting stand 2 and is provided with as many teeth as there areteeth in the ratchet-racks 52 and their semi-circular ends. Theratchet-wheel 7 3- is revolved, tooth by tooth, by the pawl 74 hung onthe end of the swinging-lever 75which is fixed to a suitable shaftmounted in a bearing 76 formed upon or attached to the stand 2. To theinner end of this shaft there is fixed the lever 77 provided with acam-roll which engages with the cam 78 fixed to the stationary part ofthe extensible-shaft 13; and each revolution of the cam 78 moves theratchet-wheel 73 one tooth.

As shown by Fig. 3, the'feeding mechanism is connected to the sleeve 7by gears and is operated by connecting the clutch 8 to the belt-pulley6, and the driving-shaft 5 is free to turn in the sleeve and isconnected to the operating-shaft of the co-acting mechanism by the gears9.

To connect or disconnect the shaft 5 from the sleeve 7 and itsattachments, the outer end of the sleeve is provided with the disk 7 9and the recessed disk 80 is fixed to the corresponding end of the shaft;the disk 79 being free to turn in the recess of 80. The latch 81 is hungto swin through a suitable slot in the disk 80 and t e spring 82 acts toswin the inner end of the latch into a 'suita le slot in the disk 79 andlock the two together, to revolve in unison. The outer end of the latch81 is extended beyond the circumference of the disk 80 and is inclined.To swing the latch clear of the disk 79 andseparate the sleeve andshaft, the guide of the curved incline 83 is fitted to slide free in asuitable bearing 84 formed the projecting inclined end of the pin 85 andto move and hold the incline 83 1n position to swing the latch 81 out ofcontact with the disk 79, removable segments 86 are fixed (bysteady-pins) to the inner side of the ratchetwheel 73, one for theheeland one for the toe. Figs. 2, 12 and 13. These segments are of suchlength, that, if their inner edges were plain they would engage with theinclined end of the pin 85 and move in, and hold the incline 83 inposition to swing the latch 81 out of contact with the disk 79 duringthe whole time the j ack-support is swinging from side to side, andthere would be no action on the ends of the last. In the inner edges ofthe segments 86 there are cut' as many recesses for the inclined end ofthe in 85 to enter as there are sections of the ast to be operated uponat the heel or toe, as shown by Figs. 12 and 13.

The normal position of the latch 81 is the slot of the disk 79 and whenthe clutch is connected to the belt-pulley the shaft 5 and the sleeverevolve in unison, and the inclined end of the latch 81 passes clear ofthe inner side of the incline 83. When the jack- I support is swingingfor the heel or toe and r it is requisite to stop the shaft and itsattachments, a plain part of the proper segment 86 contacts with the pin85 and moves the incline 83 in and there holds it. When the inclined endof the latch 81 contacts with the working-face of the incline 83 thespring 82 yields, the latch is swung clear of the disk 79 and the shaftand its attachments sto by the time the latch has reached the hig estpart of the incline 83. The stress of the spring 82 by pressing theouter end of the latch 81 against the face of the incline 83 serves tobrake the momentum of the shaft and its attachments, the only movingparts then being the belt-pulley 6, the sleeve 4, the clutch 8 and thejack-feed shaft and itsattachments. The rest of the shaft 5 continuesuntil the sleeve 7 and its attachments have made the desired number ofrevolutions the ratchet-wheel 73 moving a step for each revolution,and'finally leaving a recess in a segment opposite the pin 85. Thespring 82 then acts and swings the latch 81 into the slot in the disk79, at the same time moving the pin 85 into the recesses, and the shaftand sleeve again revolve in unison until it is again requisite to stopthe shaft, or the swinging movement of the jack-support is finished.

The vertical rise of the jack-support is alined by the groovedguide-rolls 87 mounted in pairs on the stands 88 which are secured tothe stand 2 by bolts centrally located between the pairs of guide-rolls.The stands 88 can be swung on the central bolts to adjust the bearingsof the grooved guiderolls on the guide-bars 89 and at the same time keepsaid bars in line with the jackfeed shaft 13. The ribbed guide-bars 89move vertically between the pairs of guiderolls and are secured to thetable 15 as shown in Figs. 1 and 2. i

The jack-support and its attachments and the gage'131 constitute themechanism which present the last in accurate vertical alinement of thepoint of action of the co-acting mechanism,when said arts are raised bythe elastic elevating mec anism, which comprises the balance-springs 90and the auxdiary-spring 91 wh1ch is mechanically operated as follows 2-j .The balance springs 90 are secured to the studs 90 projecting fromthe bolts holding the upper guide-roll stands, and to suitable studs 90adjustably fixed in slots in the lower ends of the guide-bars 89. Figs.1 and 2. The springs 90 are adjusted to hold the jack-support and itsattachments partiall elevated and bring the face of an inso e upon alast (on the highest curves of the last bottom) near to the contactingend of the gage 131, when said gage is elevated. When held in thismanner the jack-support and its attachments are susceptible to theslightest vertical impulse. The final rise of the jack-support and itsattachments is given by the actio of the auxiliary-spring 91 mounted inEh raised by the roll 93 mounted on and revolving with the disk 80. Theupper end of the socket-slide reciprocates in the bearing 94.- formedupon or attached to the inner sides of the stand 2 (for which it forms atie) and the lower end is slotted to pass over the sleeve 7 and isprovided with a lower face 95 upon which the roll 93 acts to raise it atthe'proper times.

Above the auxiliary-spring 91 in the socket-slide 92 there is "heplunger 96 which contacts with the under side of the table 15 andtransmits the elastic action of the sprin to give the final rise of thej ack-support and its attachments, once for each reciprocation of theco-acting mechanism as long as the latch 81 is in contact with the disk79. Mounted on. part of the co-acting mechanism, as near as possible toits point of action there is the reci rocating gage 131 which isoperated at t e proper times by said mechanism. This gage is locked downto oppose the thrust of the spring 91 and govern the vertical positionof the last in the jack by contact with the face of the sole at pointswhere action is desired on the face of said sole. It also forms theupper member of the clamp which holds the work for said action. When thejack-support and its attachments are raised by the action of theauxiliary-spring 91 to bring the face of the sole in contact with thegage 131 they form the-lower member of the holding-clamp, and when thespring 91 has reached its limit of e socket-slide 92 which is action thetable 15, the jack-support, the Y sired action upon the work clamped inthe jack. The auxiliary-spring always brings the face of the sole intointimate contact with the working end of the gage 131 with the requisiteforce, and at the same time is capable of suflicient vertical variationto antomatically provide for the variations of thickness in soles andheight of lasts.

The shipper-lever 97 swings on a shaft mounted in a bearing formed uponone of the sides of the stand 2 and is provided with the handle 98' toswing it toward the clutch 8 and stop the mechanism at any time, Figs.

1 and 2. The shipper-lever is also provided with an inclined rojection99 which enages with a simi ar projection 100 fixed on the ratchet-wheel7 3 and automatically stops the mechanism after each full revolution ofthe jack-support. To prevent the shipper-lever 97 from swinging out ofcon- 5 tact with the incline of the clutch 8 and allowing the machine tostart when not desired, the sliding spring-operated catch 101 is fittedto slide in bearings on the side of the stand 2, and when theshipper-lever is swung into position to engage with the incline of theclutch, the inclined end of the catch passes over the edge of theshipperlever and holds it as desired. To the outer end of the catch 101there is fixed the pullbutton 102 for drawin the inclined end of thecatch away from c shipper-lever and allowing the machine to start.
